Embodiment Construction

[0026]Hereinafter, some embodiments of the present invention will be described. The embodiments do not limit the invention according to the claims, and all the combinations of the features described in the embodiments are not necessarily essential to means provided by aspects of the invention.

[0027]FIG. 1 is a sectional view of the important part of a single-lens reflex camera according to the present embodiment. The single-lens reflex camera 10 is composed of a lens unit 20 and a camera body 30, to function as an image capturing apparatus. A finder unit 40 is incorporated into the camera body 30.

[0028]The lens unit 20 includes a group of lenses 21 aligned along an optical axis 11. The group of lenses 21 introduces an incident subject light flux onto the camera body 30. The group of lenses 21 includes a focus lens 23, a zoom lens 22, or the like, and is configured to move in the optical axis direction according to such an instruction as focus adjustment, field angle adjustment. The ...

Abstract

Provided is a finder unit including: a transmission-type display section that displays information as overlaid on a subject image; and a display controller that, when an illuminating section illuminates the display section, changes a first display state to a second display state, where in the first display state, a first region which is at least a part of an outer region of an effective image capturing range is displayed so that a transmission ratio of the subject image in the first region is lowered, and in the second display state, a second region which is a part of the outer region and is smaller in area than the first region is displayed so that a transmission ratio of the subject image in the second region is lowered.

Description

[0001]The contents of the following Japanese patent application are incorporated herein by reference:[0002]No. 2011-177524 filed on Aug. 15, 2011, and[0003]No. 2012-118259 filed on May 24, 2012BACKGROUND[0004]1. Technical Field[0005]The present invention relates to a finder unit, an image capturing apparatus, and a computer readable medium.[0006]2. Related Art[0007]Such cameras have been already known, which have an optical finder provided with, in the vicinity of the image forming surface, a transmission-type display apparatus adopting a polymer-dispersed liquid crystal that can switch between transmission and dispersion of light, and overlaying an AF area onto a subject optical image by bringing, to the dispersion state, the display segment corresponding to the AF area.PRIOR ART DOCUMENTPatent Document[0008][Patent Document No. 1] Japanese Patent Application Publication No. 2000-162695SUMMARY[0009]In some cases, a part of the effective pixel region of an image capturing element is...
